TDA7563APD Equivalent & Substitute Parts

Part Overview

The TDA7563APD is a 4-channel Class AB audio amplifier IC manufactured by STMicroelectronics, housed in a PowerSO-36 package with exposed top pad. This device delivers 75W per channel at 2Ω load impedance and integrates I2C control, mute functionality, short-circuit protection, thermal protection, and standby mode. The TDA7563APD is classified as obsolete, making identification of equivalent substitute parts essential for ongoing design support and production continuity. Direct substitutes must maintain identical electrical performance, package compatibility, and feature set to ensure seamless integration into existing circuit designs.

Substitute Part Grouping Explanation

Substitution of the TDA7563APD is determined by strict equivalence across the following critical parameters:

Electrical Performance Criteria:

Amplifier topology (Class AB)
Channel count (4-channel quad configuration)
Output power specification (75W per channel at 2Ω load)
Supply voltage operating range (8V to 18V)
Integrated protection and control features (I2C, mute, short-circuit protection, thermal protection, standby mode)
Operating temperature range (-55°C to 150°C junction temperature)

Physical and Manufacturing Criteria:

Package type (PowerSO-36 with exposed top pad)
Mounting technology (surface mount)
Moisture sensitivity classification (MSL 3)
Regulatory compliance (ROHS3, REACH Unaffected, EAR99)

Substitute parts must match all parameters listed above. Deviations in any electrical specification, package configuration, or compliance status disqualify a part from direct substitution.

Engineering Selection Recommendations

The TDA7563BPD is a direct electrical and mechanical equivalent to the TDA7563APD. Both devices share identical specifications across all critical performance parameters, package configuration, and regulatory compliance certifications.

Selection Basis:

The TDA7563BPD is the recommended substitute for the obsolete TDA7563APD. The substitute part maintains full compatibility with existing PCB layouts, thermal management designs, and firmware implementations. Both parts are manufactured by STMicroelectronics under the same base product number (TDA7563) and carry equivalent ROHS3 and REACH compliance status.

The primary distinction between the two parts is product lifecycle status: the TDA7563APD is obsolete, while the TDA7563BPD is active in production. This status difference ensures long-term availability and supply chain continuity for the TDA7563BPD.

No design modifications, PCB rework, or firmware updates are required when transitioning from TDA7563APD to TDA7563BPD. Pin-to-pin compatibility, electrical performance, and thermal characteristics remain unchanged.
